Feynman Parametrization and the Degenerate Electron Gas

arXiv:hep-ph/9209273 · doi:10.1103/PhysRevD.47.601

Abstract

We give an alternate derivation of Weldon's formula for combining products of factors with non identical analytic behavior. While such a formula would appear to be useful in finite temperature calculations, we give an example of a zero temperature calculation, namely, the degenerate electron gas, to justify the result.
